On the fifth day of December, my internet friend gave to me: another Winter Holiday Trivia question!
Introduced in the 16th century, this calendar resulted in the loss of 11 days in the calendar year and moved Christmas to December 25 (well, sort of ... Christmas had already been set as December 25 as early as the fourth century).
What is the name of this calendar? Feel free to submit your answer in the comments!
Note: This video has nothing to do with today's trivia question.
